修改母版页内容

1、使用Title属性
<%@Page Language="c#" MasterPageFile="~/SimpleMaster.master" Title="Content Page File" %>
....

2、使用Page Header属性
  如果需要通过编程方式修改母版页的页标题或CSS规则，可以使用Page.Header属性，返回一个实现IPageHeader接口的对象。
具有以下属性
StyleSheet
Title
<%@ Page Title="" Language="C#" MasterPageFile="~/SectionProducts.master" %><script runat="server"> protected void Page_Load(object sender, EventArgs e) {       Page.Header.Title = String.Format("Header Content ({0})", DateTime.Now);       Style myStyle = new Style();       myStyle.BackColor = System.Drawing.Color.Red;       Page.Header.StyleSheet.CreateStyleRule(myStyle, null, "html"); }</script><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHoder1" runat="Server"> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products</asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHoder2" runat="Server"> Products,Products,Products 2 <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products</asp:Content><asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHoder3" runat="Server"> Products,Products,Products 3 <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products <br /> Products,Products,Products</asp:Content>

Meta
<%@ Page Title="" Language="C#" MasterPageFile="~/SectionServices.master" %><script runat="server"> protected void Page_Load(object sender, EventArgs e) {       //Create Meta Description       HtmlMeta metaDesc = new HtmlMeta();       metaDesc.Name = "DESCRIPTION";       metaDesc.Content = "A sample of using HtmlMeta controls";       //Create Meta Keywords       HtmlMeta metaKeyword = new HtmlMeta();       metaKeyword.Name = "KEYWORD";       metaKeyword.Content = "HtmlMeta,Page.Hader,ASP.NET";       HtmlHead head = (HtmlHead)Page.Header;       head.Controls.Add(metaDesc);       head.Controls.Add(metaKeyword); }</script><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHoder1" runat="Server"> Services,Services,Services 1 <br /> Services,Services,Services <br /> Services,Services,Services <br /> Services,Services,Services <br /> Services,Services,Services</asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHoder2" runat="Server"> Services,Services,Services 2 <br /> Services,Services,Services <br /> Services,Services,Services <br /> Services,Services,Services <br /> Services,Services,Services</asp:Content>
页面多生成如下内容：
</title>
<meta name="DESCRIPTION" content="A sample of using HtmlMeta controls" />
<meta name="KEYWORD" content="HtmlMeta,Page.Hader,ASP.NET" />
</head>

3、暴露母版页属性
  可以将母版页中的属性和方法暴露出来，然后在特定的内容页中修改这些属性和方法。
PropertyMaster.master
<%@ Master Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> public string BodyTitle {       get { return ltlBodyTitle.Text; }       set { ltlBodyTitle.Text = value; } }</script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <style type="text/css">       html       {          background-color: Silver;       }       .content       {          margin: auto;          width: 700px;          background-color: White;          padding: 10px;       }       h1       {          border-bottom: solid 1px blue;       } </style> <title></title></head><body> <form id="form1" runat="server"> <div>       <h1>          <asp:Literal ID="ltlBodyTitle" runat="server" /></h1>       <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">       </asp:ContentPlaceHolder> </div> </form></body></html>

propertyContent.aspx
<%@ Page Title="" Language="C#" MasterPageFile="~/PropertyMaster.master" %><%@ MasterType VirtualPath="~/PropertyMaster.master" %><script runat="server"> protected void Page_Load(object sender, EventArgs e) {       if (!Page.IsPostBack)       {          Master.BodyTitle = "The Body Title";       } }</script><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server"> Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content</asp:Content>

注意点：
  1)<script runat="server">
public string BodyTitle
{
      get { return ltlBodyTitle.Text; }
      set { ltlBodyTitle.Text = value; }
}
</script>
  2)内容页必须加上
<%@ MasterType VirtualPath="~/PropertyMaster.master" %>

4、对母版页使用FindControl方法
FindMaster.master
<%@ Master Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"></script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <style type="text/css"> html {    background-color:Silver;    }    .content    {       margin:auto;       width:700px;          background-color:White;          padding;10px;       }       h1       {             border-bottom:solid 1px blue;          }</style> <title>Find Master</title></head><body> <form id="form1" runat="server"> <div class="content">       <h1>          <asp:Literal ID="ltlBodyTitle" runat="server" /></h1>       <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">       </asp:ContentPlaceHolder> </div> </form></body></html>

FindContent.aspx
<%@ Page Title="" Language="C#" MasterPageFile="~/FindMaster.master" %><script runat="server"> protected void Page_Load(object sender, EventArgs e) {       if (!Page.IsPostBack)       {                      Literal ltlBodyTitle = (Literal)Master.FindControl("ltlBodyTitle");          ltlBodyTitle.Text = "The Body Title";       } }</script><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">  Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content <br /> Content,Content,Content,Content</asp:Content>
